I happened to see Mr Duff.s camouflage table on the Model Warships site, and going through it I could not find the colour G40, which came into use in late 1944.

Also, there were several shades of mountbatten Pink that went right down to where the light mediterranean grey of pre war use had a touch of red put in. This is worth mentioning I feel.

In the period leading up to WW1, each command, ie, Portsmouth, Plymouth and others used a different shade of grey so as to visually distinguish between ships of different commands. This information came from a retired constructor and a couple of very old sailors who had good memories. Each of their stories added up. Do with it what you will. Photos, even allowing for the many variables, appear to give some confirmation.
